Abstract:Immiscible two-phase flow in porous media is crucial in various industrial processes, necessitating a robust numerical tool to capture this complex multiscale behavior. This paper aims to introduce a novel micro-continuum multiphase solver, abbreviated as DBS-CG, which integrates lattice Boltzmann method with the Darcy–Brinkman–Stokes approach via embedding a volume-averaging scheme into the color-gradient model. The fluid–solid interactions in free and porous regions are effectively reproduced by the continuu… Show more
